Goblin Commandos v1 by jeffn516 This example and accompanying .erf show two examples of how a DM can communicate in character to control more than one character. The first method illustrates the use of listen patterns in a pseudo-goblin tongue in order to command your troops either follow you or scatter. Simply say glaabruza -- to gather your allies to you zezo -- to scatter them Goblins will respond to you if they can hear what you have said. Additional commands can be added by reviewing the sc_gob_oc and sc_gob_os files and making the appropriate changes. An alternate method of communication is to use the conversations on these goblins (again, you'll need to be friendly to them to get close enough to use these and not get attacked). Options are provided to allow the goblin follow you (ala 'glaabruza') or follow you and change their faction to defender.
Voice activated set of goblins. As a DM you just need to speak the goblin words included and they will respond and obey your commands.
